Photonic technologies for endoscopic and laparoscopic surgical guidance

Research output: Contribution to conferenceAbstract


Photonics-based technologies present attractive scope in assisting endocavitary surgery. Optical coherence tomography (OCT) uses light to produce cross-sectional tissue images at the microscopic detail level, thereby enabling morphological information to be assessed non-invasively. Complementarily, Raman spectroscopy offers a technique that provides biochemical fingerprints of biological tissue, while spectral analysis of the backscattered infrared light from tissues (NIRS) yields information on the local tissue metabolism.
The use of OCT, Raman spectroscopy and NIRS for the guidance of a second-generation surgical robot, and of NIRS for assistance to epiduroscopic navigation will be reported. NIRS data measured on a dedicated epiduroscopy phantom will also be presented.
